11/0.4kv 3-Phase Copper Power Distribution Oil Immersed Transformer
Features
Load-ratio voltage regulation, high reliability, advanced level of performances, reasonable economical indicators.
The core joints are of stepped shape with 3 steps, and the surface of the core is coated with cured paint to lower losses and noise.
The winding has novel structure and its oil passage is reasonable designed. Its newly designed insulation structure helps enhance its mechanical strength and the short circuit withstanding ability.
The oil tank is in two types-fully enclosed type and the type fitted with an oil conservator.
